Mnemonic

Late at night, a faint whisper drifts through the house. Someone is at the door beneath your roof. You open it to find a drenched guest, whispering desperately for shelter. You pull the guest inside, and under your warm roof, the whisper fades into grateful silence.
Additional thoughts
Picture standing in a dark hallway, hearing that eerie whisper, then seeing a soaked traveler at the door. The roof shelters, the whisper beckons — that's how a guest arrives uninvited on a stormy night.
